I guarantee you it is not clipping when the OPPO Picture Adjustment settings are all set at their factory default (0) values.
The Dynamic Range High chart on Spears & Munsil shows separate, blinking bars for each individual Luma value from just below Reference White, through Reference White, and through the entire range of Peak Whites if the Display is able to reproduce those. On the 103, they are *ALL* distinguishable from the maximum Luma value (the bright white background of the chart) on a Display that can reproduce those, regardless of whether you are using YCbCr 4:4:4, YCbCr 4:2:2, or RGB Video Level output format.
The output is identical to that of other players known to properly pass Peak Whites -- e.g., the PS3 when set to YCbCr 4:4:4 with SuperWhite enabled.
In addition, OPPO has digital HDMI data captures of the output stream (part of their engineering bench testing) which show the high Luma values all being passed correctly -- a test which is, of course, independent of what any given AVR or Display might do with that output.
